MOUNTING FOR CAR AXLES Filed March 2, 193i 2 sheets-sheer 2 Patented Sept. 29, 1931` uNlTEDsTAT-Es PATENT or-FlcaJ ELMEYRVLATSHAW, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR T THE J'. G.

The object of my invention is to mount an axle box within a cushion of rubber or other resilient material.

- A further object of the invention is to provide a cushion between the axle box and the frame, which will absorb shocks and which will prevent the transmission of vibrations and metallic sounds from the wheels to the truck frame and car body.

A still further object of the invention is to mount the journal box so that there is a full universal action of the journal box with respect to the yoke. This is permitted by the use of a ring of rubber or other resilient lli material mounted between the axle box and the frame.- c

In the accompanying drawings.:

F Fig. 2 is a sectional view on the line 2 2, ig. 1; l

Fig. 3 is a detached pers ective view of the rmg of resilient materia, in the present instance, rubber; and

F Fig. 4 is a sectional view on the line 4&4,

i. lgis'the frame of the car. truck, having a segmental end bearing 2 and pivoted at 3 tothe outer end of the frame is a segmental clamp member 4, which Vis secured to the segmental end of the frame. TheV` clamp member has a lug 5 and'the frame has a lug 6. Extending through the two lugs is a bolt 7, on which is a washer and a nut 8.

Inthe present instance there is a tie bar 9, which extends'from one end of the truck to the other end thereof, and this tie bar is bent upwards and is located between the lug on the frame 1 of the truck and the lug 5 13 for the axle. The inner end of the journal .box is -grooved as at 14, and located in.

the groove is a dust guard 15. 16 is the Wheel of the car truck. While one form of journal box is shown, it will be understood that diii'erent types of journal boxes may be on the clamp member, and this bar is preferused Without departing from the essential features of the invention.

The segmental end 2 of the body of the truck has an internal groove 17, and the segmental clamp member 4 has a like groove 18. On the journal box `are formed two annular ribs 19 and these ribs are spaced a art sov as to' form a groove 2 0. 21 is a ring o resilient material, which in the'present instance is rubber and is rectangular in cross section. The periphery of this ring extends into the grooves 17 and 18 of the truck frame 1 and segment-al member 4, while the inner portion is located in the groove of the journal box, so that the, box is entirely surrounded by the resilient rubber ring: The grooves are of such depth that the ring will be held in place between the journal box and the frame. In the present instance the ring is split at 22 and the ends abut against ribs 23 and 24 on the clamping member 4 and the journal box respectivelygireventing the ring turning in the the vertical or car body load is cushioned between'the journal box and the side frame by the rubbery ring, which absorbs shocks and prevents the transmission of vibration and metallic sounds from the wheels to the truck frame and car body. The fact that the rubber will sufficiently cushion the load with a very small amount of deflection, means that the brake shoe position on the wheels will vary slightly with that of the passenger load. When the motors are driven inl either direction, the horizontal force is transmitted from the journal box from the frame through the rubber cushion. Thus the rubber eliminates the usual noises occurring when a journal box is forced against the pedestals in the conventional design. The lateral force originating at theV wheel anges when the car is rounding a curve, is insulated with respect nal boxes in the manner described, permits a full universal action of the journal box with respect to the yoke, which action is permitted by the yield in the rubber ring. This allows the use of any type of anti-friction bearing.

In the drawings I have shown a solid rin of rubber located between the ournal box an the bearing but it will be un erstood that' in some instances the may be tubular so that the ring may be ated without departing from the essential features of the invention.

I claim:

1. The combination in a car truck, of a fframe having a segmental end bearing; a-

segmental clamp member pivoted to the said end bearin means for securing the twola parts toget er; a cylindrical journal box; and a ring of resilient material located between the bearing, the segmental member and the cylindrical journal box.

2. The combination in a car truck, of a fra-me having a segmental bearing; a segmental clamp member pivotally connected to said bearing, and means for securing the two parts together, each part having an interior groove therein; a cylindrical journal box having an external groove; and a resilient ring surrounding the journal box and extending into the grooves ofthe journal box and the bearing and segmental clamp member.

3. The combination in a car truck, of `a frame having a segmental end bearing; a

, segmental clamp member; a pivot pin pivotally connected to the se entalV end bearing, the end bearing and t e se ental ,clamp member having lugs and a olt extending through the lugs, securing the two partstogether, each part having an internal groove therein; a cylindrical journal box having an external groove; and a resilient ring mounted between the journal box, the bearing and the segmental clamp member, the ring extenda ing mto the groove in the journal box and the groove in said members.

4. The combination in a car truck, of a frame having a segmental end bearing; a segmental clamp member pivoted to the end and a tie-rod located between the free ends of the two parts and secured to the frame at the bearing; means for securing the segmental clamp member to the end bearing; a cyllndrical journal box; and a ring o'f resilient material located between the journal box bald the bearing and segmental clamp mem- 5. The combination in a car truck, of a frame having a segmental end bearing; a segmental clamp member pivoted -to the segmental bearing, each part having a lug opposite the pivot; a tie-rod extending between the two lugs and welded to the lug of the segmental bearing; a bolt extending through the two lugs and the end of the rod; a cylinthe ring turning.
